I "brown bag" it mostly for economy, and partly because my leftovers are generally better than anything else around.
It's funny---the shot from Gary's orig. post reminded me that when I worked retail some 15 yrs. ago at Crate & Barrel, the building maintenance guys were an all Polish crew. We all shared a break room, and while the sales folks brought in sandwiches or Ameri-Thai take-out, the maintenance guys routinely brought tins of sardines, dense Polish rye and onions. They were relentlessly mocked, sotto voce, by the sales staff of recent grads small college now enrolled at Harrington. And I always wondered just how different the little debs thought their tuna salad sandwiches were, from the fork mashed sardines they thought were so "gross."
Lately my favorite desk lunch is a quasi-Middle Eastern collation of feta, olives, celery, carrot, and sticks, tomato, and sometimes some slices of salami or left over grilled meat with toasted pita. I just drizzle all the ingredients with good oil and a squeeze of lemon and let it marinate till lunch time. Not as fragrant as sardine and onion, while still packing a very spiritied flavor punch. It's also bright and colorful enough that people pass by and ask, "Oooh, what's that!" instead of "ewww gross!" as with either Indian/Pak. lunch, or mashed sardines, etc.
I'm also a big fan of various bean salads as a great one-dish desk lunch. Beans are so accomodating to whatever else is in the fridge from Saturday's trip to Green Market. Chop some fresh herbs, squeeze on fresh lemon and oil, and it all just takes care of itself.
Right now I"m munching some of those lovely, not-too-sweet, round, poppy-filled, sesame-topped cookies from Kayam bakery with my coffee (also brought from home, needless to say).
